Abstract
Systems, devices, and methods for transparent displays that are well-suited for use in wearable heads-up displays are described. Such transparent displays include a register of light-emitting diodes that sequentially generates pixels or other discrete portions of an image. Respective sets of light signals corresponding to the respective portions (e.g., rows) of the image are sequentially directed into the user's field of view by a combination of a dynamic reflector and a set of static light-redirection elements. The dynamic reflector is an elongated reflective strip (including, for example, one or more MEMS-based digital micromirror(s)) mounted outside of the field of view of the user and the set of static light-redirection elements are substantially transparent and mounted directly in a field of view of the user. Successive portions of the image are generated in rapid succession until the entire image is displayed to the user.
